Age: 7 years
Duration: 40 minutes of 3 periods
Date:
Subject: Basic Science and Technology
Topic:- Air (Wind)
- Classification of computer by generation
- Safety education
SPECIFIC OBJECTIVES: At the end of the lesson, pupils should be able to
INSTRUCTIONAL TECHNIQUES: Identification, explanation, playway method, questions and answers, demonstration
INSTRUCTIONAL MATERIALS: piece of paper, feathers, charts showing the effects of wind etc, pictures of fourth and fifth generation of computers, hand fans, kite, balloons, first aid kits
PERIOD 1: Wind
PRESENTATION | TEACHER’S ACTIVITY | PUPIL’S ACTIVITY |
STEP 1 INTRODUCTION | The teacher revisits the previous lesson on developed and underdeveloped technology and introduces the new topic by allowing the class to brainstorm and formulate the meaning and causes of wind by watching video clips
| Pupils pay attention |
STEP 2 EXPLANATION | The teacher then explains what wind mean- wind simply means air in motion She further explains that the effects of wind could either be useful or harmful | Pupils pay attention and participates |
STEP 3 DEMONSTRATION | Using live examples, the teacher explains the useful effects of wind A gentle wind is called BREEZE 1. wind is a source of energy 2. wind is used for sailing boats, ship etc 3. wind is used in flying kites, airplanes etc 4. it is useful in separating chaffs from grain 5. it helps us to move effectively 6. it cools our body and environment 7. it helps in the growth of plants and crops
The teacher then demonstrates how wind work y using hand fan, kite, balloon and balls | Pupils pay attention and participate |
STEP 4 NOTE TAKING | The teacher writes a short note on the board | The pupils copy the note in their books |
NOTE
Wind simply means air in motion. The effects of wind could either be useful or harmful
Useful effects of wind
A gentle wind is called BREEZE
EVALUATION: 1. What is wind?
CLASS ACTIVITY: Pupils in small groups, analyse why wind is essential
CLASSWORK: As in evaluation
CONCLUSION: The teacher commends the pupils positively
PERIOD 2 and 3: Classification of computer by generation. Safety education
PRESENTATION | TEACHER’S ACTIVITY | PUPIL’S ACTIVITY |
STEP 1 INTRODUCTION | The teacher revisits the previous lesson on first, second and third generations of computers
| Pupils pay attention |
STEP 2 EXPLANATION | The teacher then explains fourth and fifth generations of computers
FOURTH GENERATION(1971-1980) Fourth-generation computers used microprocessors which were designed using the LSI (Large Scale Integration) and VLSI (Very Large-Scale Integration) technology. The computers became small, portable, reliable and cheap. The computation time is in picoseconds. They became available both to the home user and for commercial use.
FIFTH GENERATION(1982-date) Fifth-generation computers are expected to be capable of learning and self-organization. The computers use SLSI (Super Large-Scale Integration) chips and have large memory requirements. They use parallel processing and are based on (AI) Artificial Intelligence. The fifth-generation computers are still being developed. | Pupils pay attention and participates |
STEP 3 DEMONSTRATION | The teacher explains the meaning of safety education
Safety education is a series of instructions and warnings that provides awareness about possible harms and injuries with an objective of minimizing injuries and their fatal consequences
The teacher then outlines the safety education conditions for first aid treatment 1. Put on gloves, nose mask and other safety apparel before administering first aid treatment 2. Attend to bleeding first 3. Keep the crowd away from the victim 4. if you don’t have adequate knowledge about first aid, don’t administer it 5. Call for ambulance or rush the victim to the hospital once first aid has been administered | Pupils pay attention and participate |
STEP 4 NOTE TAKING | The teacher writes a short note on the board | The pupils copy the note in their books |

FIFTH GENERATION (1982-date)
Fifth-generation computers are expected to be capable of learning and self
organization. The computers use SLSI (Super Large-Scale Integration)
chips and have large memory requirements. They use parallel processing
and are based on (AI) Artificial Intelligence. The fifth-generation computers
are still being developed.
Safety education
Safety education is a series of instructions and warnings that provides awareness about possible harms and injuries with an objective of minimizing injuries and their fatal consequences
Safety education conditions for first aid treatment
EVALUATION: 1. Describe the fourth generation of computers
CLASS ACTIVITY: Pupils, as a class discuss the fourth and fifth generation of computers
CLASSWORK: As in evaluation
CONCLUSION: The teacher commends the pupils positively
